Pope Francis poses with the Diplomatic Corps accredited to the Holy See at the Ducale Hall in the Apostolic Palace at the Vatican on March 22; 2013. (pape Francois - Palais Apostolique - Salle ducale)The Sala Ducale (salle ducale) is in the oldest part of the Vatican Apostolic Palace; built during the time of Popes Innocent II (1198-1216) and Nicolas III (1277-1280). The space was used for of?cial ceremonies to receive important personalities; such as the 'Dukes of highest power;' thus resulting in its name; the Ducal Hall. Initially upon entering the hall; what is immediately striking to the eye is the spectacular arch; dressed in sumptuous drapery. The illusion of fabric upheld by putti; or little cherubs; is actually a creative work in stucco by the great sculptor Gian Lorenzo Bernini (1598-1680). The artist was commissioned by Pope Alexander VII (1655-1667); and entrusted the physical execution to Antonio Raggi (1624-1686); one of his most valuable aids. -The grandiose and solemn Apostolic Palace is a secretive place; forbidden to the public and jealously guarded by the Swiss Guard. It hosts the Holy See administration; the Church's spiritual authorities and before all; the apartments of the Pontiff Sovereign.
